Can you have a healthy democracy without a common set of facts?

Journalists should not spend much of their time writing about journalism. The world is more interesting than the inky habits of the people who report on it. But this week we are making an exception, because the discovery and dissemination of information matters a lot to politics. Don’t take our word for it: “A popular government,” wrote James Madison in 1822, “without popular information, or the means of acquiring it, is but a prologue to a farce or a tragedy; or, perhaps both.” Were Thomas Jefferson offered a choice between a government without newspapers and newspapers without a government, he said that he would choose the press (though that is probably going a bit far).As the turmoil at America’s elite universities over antisemitism shows, creating a political culture in which people can argue constructively, disagree and compromise is not something that happens spontaneously. In media, business models, technology and culture can work together to create those conditions. They can also pull in the opposite direction. Our analysis of over 600,000 pieces of written and television journalism shows that the language of the mainstream American media has drifted away from the political centre, towards the Democratic Party’s preferred terminology and topics. That could lower the among conservatives.
